Properly implemented, computer control will provide:
* Rotator control,
* Full Doppler correction.
And yes - you can rag-chew without turning too many dials but currently with
FO-29 'resting' you'll only be able to use VO-52 and get up to 10-15 minutes
quality time on a pass. (You shouldn't hog an FM-only satellite such as
AO-51 or SO-50.)
P3E will be a different matter, you'll be able to talk for hours when it's
visible.
